Guardian Air Vents proven design provides more air release capacity than other vents of similar size. Commonly used to break vacuum caused by sytem draining.

These valves have been designed for efficient discharge and intake of air in water transport systems, filtering systems, containers and other places where confined air could impair the system's operation.  
- Expels the air at high flow velocity during the initial filling of the system.
- Introduces large quantities of air when the pipe drains, while maintaining atmospheric pressures in the pipe. 

Product Advantages:

  • Ensures maximum protection of the irrigation system with proper sizing and placement.
  • Ensures vent closure as water fills the system, remains open when air pressure reaches the following:
    • 5 psi for 3/4" and 1" Guardian
    • 10 psi for 2" Guardian
    • 8 psi for 3" Guardian
  • Large capacity vents dampen water hammer preventing pipes and fittings from cracking or bursting.
  • Made of corrosion-resistant reinforced UV protected composite materials - no metal parts to rust or corrode, no need for spare parts.
  • Guardian Air Vent with Shrader Valve is ideal for measuring local line pressure.

Applications:

  • Commonly used downstream of valves, primarily at manifolds, to break vacuum caused by system draining.
  • On sloping terrain to prevent collapsing of pipes caused by vacuum when pipe networks drain.
  • Upstream of valves for air discharge during system start-up.
  • 1" and 2" Combination Air/Vacuum and Continuous Acting Air Vents
    • For discharge and intake of large volumes of air at pump and filtration stations, along mains and at the end of mainlines.
    • For continuous air release at high points in pipe network or upstream of manifolds.
    • Every 1,500 feet along mainlines.
  • 2" Combination Air Release/Vacuum Guard and Continuous Acting Air Vent
    • Releases air at pump priming and maintains the prime by not allowing air intake in long and/or undulating suction lines to pump stations.
    • Releases entrapped air while ensuring continuous prime at centrifugal pumps.
    • Builds up siphons with air release, maintains the siphon by continuously releasing air and not allowing air intake.
